ide-cd: temporary tray close fix

2008-10-05T16:23:27+00:00

This one fixes http://bugzilla.kernel.org/show_bug.cgi?id=11602.

A more generic fix for drives which cannot autoclose tray will follow.

mm: tiny-shmem nommu fix

2008-10-02T22:53:13+00:00

The previous patch db203d53d474aa068984e409d807628f5841da1b ("mm:
tiny-shmem fix lock ordering: mmap_sem vs i_mutex") to fix the lock
ordering in tiny-shmem breaks shared anonymous and IPC memory on NOMMU
architectures because it was using the expanding truncate to signal ramfs
to allocate a physically contiguous RAM backing the inode (otherwise it is
unusable for "memory mapping" it to userspace).

However do_truncate is what caused the lock ordering error, due to it
taking i_mutex.  In this case, we can actually just call ramfs directly to
allocate memory for the mapping, rather than go via truncate.

hrtimer: prevent migration of per CPU hrtimers

2008-09-29T15:09:14+00:00

Impact: per CPU hrtimers can be migrated from a dead CPU

The hrtimer code has no knowledge about per CPU timers, but we need to
prevent the migration of such timers and warn when such a timer is
active at migration time.

Explicitely mark the timers as per CPU and use a more understandable
mode descriptor for the interrupts safe unlocked callback mode, which
is used by hrtimer_sleeper and the scheduler code.

hrtimer: mark migration state

2008-09-29T15:09:14+00:00

Impact: during migration active hrtimers can be seen as inactive

The migration code removes the hrtimers from the queues of the dead
CPU and sets the state temporary to INACTIVE. The enqueue code sets it
to ACTIVE/PENDING again.

Prevent that the wrong state can be seen by using a separate migration
state bit.

smb.h: do not include linux/time.h in userspace

2008-09-23T15:09:13+00:00

linux/time.h conflicts with time.h from glibc

It breaks building smbmount from samba.  It's regression introduced by
commit 76308da (" smb.h: uses struct timespec but didn't include
linux/time.h").

Fix PNP build failure, bugzilla #11276

2008-09-17T02:35:05+00:00

This fill fix the following regression list entry:

Bug-Entry	: http://bugzilla.kernel.org/show_bug.cgi?id=11276
Subject		: build error: CONFIG_OPTIMIZE_INLINING=y causes gcc 4.2 to do stupid things
Submitter	: Randy Dunlap 
Date		: 2008-08-06 17:18 (38 days old)
References	: http://marc.info/?l=linux-kernel&m=121804329014332&w=4

Handled-By	: Bjorn Helgaas 
Patch		: http://lkml.org/lkml/2008/7/22/364

with what I believe is a better fix than the one referenced
in the regression entry above.

These PNP header interfaces try to work in such a way that
you can reference some of them even if PNP is not enabled,
and the compiler was expected to optimize everything away.

Which is mostly fine, except that there was one interface
for which there was not provided an inline "NOP" implementation.

Once we add that, all of these compile failures cannot handle
any more.

pnp: Provide NOP inline implementation of pnp_get_resource() when !PNP

Fixes kernel bugzilla #11276.
